I bought and used an el cheapo SD Card (which claims life time warranty) to took pictures and recorded videos. However when I tried to transfer the file it became corrupt and my PC ask if I wanted to format the SD Card.

I browsed and found PC Inspector File Recovery to recover the pictures and videos.

I managed to save pictures perfectly but when I restore video there is no sound at all. Video quality is not affected and I think file size is still the same so I assume sound information is still there but for some reason it cannot be extracted.
